TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Sept. 29, 1914.

Application led December 4, 1912; ,Serial No. 734,869.

To ZZ 2li/loinl it muy wmf-ern Be it known that l, lvmman J. Nenne, acitizen ot the United States, residing at Madison. in the county olDane, State of ll'isconsin, have invented a certain new and usefulImprovement in Type-lVriting Machines, ot' which the following is aspecification. reference beingr had therein to the accompanying"drawings.

Certain principles and features of my invention as described herein areincluded within the generic invention which is described and Yclaimed inLetters Patent. No. 1.053.915). granted Feb. 1S, 1013, upon myeo-pending application filed April 20, 1908, Serial No. 428,212. l

(lne ot the. objects of my general invention is to indicate to theoperator of a typewriting mat-ine the` decreasing distance from thecurrent printing point to the, bottom end of the sheet, and this withoutpreliminary care on his part, automatically. Other objects are to supplyhim with improred indicating means of various-types for indicating thearrival of the sheet into a predetermined line position.

T he lpresent branch or division of the invention has as featurescertain novel constructions and combinations adapted to render theinvention more useful in practice. including a novel form ofreciprocating paperffeele a novel use ot a cam and cam-l r'olloaa'er inpaper-conto)lled devices: an imloecarrier of novel construction: a novelrmfihination of elements making' use of a ferienretrarting- Spring; aspecial form of light-:ritme bell-signal and mzuhine-loclisignalmechanism adapted l'or use with the ariualing means herein shown; andother novel f'w-mstrru'tions and combinations, as will he hereinafterexplained. l

lVith reference to the d1awings,-Carringe frame 12', movable laterallyin usual Fig. is a frontvlew ot the same, with the platen frame inmanner upon the main frame 41 of theA typewriting machine. has mountedupon it shifting' platen frame a7, supplied with the usual supportingand controlling meohef nism, journaled in the ends of which is platenarbor 13 hearing platen head 89 ot the sheet-advancing` platen-roll 10.operated by line spacing mechanism as in practice and not shown herein.The usual paper table for the support of the entering sheet is indicatedat 8, the same being carried in usual manner upon the .platen trame et?.Typewriter structure such as is referred to is well-known and need notbe more closely described herein. In applying au embodiment of thepresent invention to this strueture (Fig. 9) against the end ot' theplaten '1U is placed. a friction washer 1l, preter ablj,y made ot'leather or cardboard. The washer 1s not essential. Against the washer isplaced' operat1ve member (i,

through. which the several types ot indicationy means desired to beemployed are called into operation. As here shown, this member isiourualed upon platen-head 3) and is const1'uct '.l asan annular shellharing; an internal shoulder. Aga-inst said shoulder bears athrust-rin;r St of sheet-metal a flange ot' which receivesaxially-directed pressure from a diaphramn spring` 7. Member G bears aproieetion 1l.; used also as a key-pin to keep spring Z than shifting`angularly thereon. Thrust-ring Si is discontinuous.

c.. a split ring. the projection passing' between the two ends thereof.Diaphragm Spring 7 may it desired openings, like that shown spin withradial relieve the the spring spring 7 is preferably supplied slits 31(Fig. fl) in order to transverse strains and render moreliexible, thougha 1n Fig. 5, at 7 lmay be used, or one with other than radial openings,like that shown in Fig. 6 at 7b. he protected from the Wear ofthrust-collar 33, attached upon platenLhead 39 by means ot set-screw 9,by a thrust-Washer 35, conveniently attached to said spring by rivets61. Dish 25, conveniently attached by means of the same rivets, isprovided with threaded seats or holes 67, into one of which may besere-Wed a pin 68, through suitable openings inthe Preferably ,by meansof hol'oelarnpsV i6 and spring-clamp 46 platen-frame l? has attachedagainst the fiat inner side thereoi a rameplate 2 (Fig. f5), which is soshaped as to receive additional support from the K cross-brace of thesaid trame. The purpose being increased.

spring-post or 82 to `initial or normal position as shown of the plateis to supply supporting structure for my mechanism without altering theexisting structure of the machine; but it could of course be changed in:torni and vmanner of attaching, or omitted altogether, as shown insome' ot my other ligures. llate 2 bears an inwardly projecting pin 2O(Fie. 8), which has independently journaled upon it end to end thebushings .or hubs 2l and 21 bearing respectively arm 32 and cam-stop.

15. Stop 15 acts both as a'stop and as a lever-it'normally lies in thepath oi pin' 14, upon which it acts as a stopfbut it is in turn actedupon by said pin and acts upon arm 32 and papenfeeler 28 thereon as alever. Weight 111 tends to restore said stop into the path of said pin,le. The stop Ais preferably constructed cani-shaped and han ing a camsurface 3G, the purpose of the cam' form being-first, to give the stopas rapid action as may be desired under the actuation of pin 14,second,to increase its angle of engagement with said pin and thereforeits range of movement under the actuation thereof,` and third, to lessenthe pressure of paper-feeler 28 upon the sheet under the actuation orpin le; and it has other ativan tages. Said step is therefore a cam, andpin 14 is a cam follower. The position of axle 20 within the aredescribed by pin 1a results in advantages in operation, the leverageloeing more readily made to favor the sheet and the engaging angle oi'pin ifi and stop 15 A spring 66 attached to pin 64% on plate 2 restoresarm in Fig. 3. Arm 32 supplied also with lugs 63 to cooperate with`projection 52 on Weight 111, forming a Oneway joint or knucklejoint, thepurpose oi the prm'ision being to supply a baelrinnfup means torpin 1ipast stop 15. Arm 32 bears the iixcdly attached spring without,

transversely extending paper feeler 28, which in the form shown in Figs.1, 3, 7, l2, 13, maintains a position substantially parallel with theplaten anis.` Said papel-techar has a path through the slot or opening iin` the paper-supporting structure 81, preferably clamped upon rod 18 bymeans of bolt 19. l prefer to use a simple form of paper- ;teeler likethe straight pin shown, having a path through a slot shaped tocorrespond. Such a paper-feeler presents a minimum ob struction to thebacking-up bottom edge of the sheet, instantly frees itself ot it, canbe 'made to reach as far past the printing mar gin .fr as is desirable,is strong, is simple of manufacture, has small inertia, can be open atedin a cramped space, and by reason of its normal position against theplaten is protected from injury bythe platen.

The operation of this ortionof the mechanism is as follows: A s eet ofpaper is inserted in usual manner and fed forward through theinstrumentality of the platen. As the platen turns, member 6,frietionally connected therewith, also turns, together with projectionla carried thereon. Eventually projection 14 meets Acam surface 30 uponcam-stop l5 and rocks the cam-stop upon its axis'QO. This action iscommunicated through projection V(32 to arm 3Q until paper-eeler 9.8meets sheet 45, as shown in Fig. 1. As .paper-feeler 28 cannot passthrough slot Ll duringthe presence of the sheet over the slot,and ascam-stop l'cannot pass out of the way o projection 1l until the feelerpasses through said slot, member 6 is stopped until the bottom edge ofthe sheet clears slot e.- The moment the sheet clears the slot, however,paper-eeler 28,- no longer detained by the sheet, passes through theslot, and member, 6, no longer detainedA by stop 15, takes up itsmovement with the platen. As member G begins its movement always whenthe bottoni edge ot the sheet is a fixed distance from the' printingpoint, and maintains always a progress thereafter coordinated with that'of the sheet, bringing always the same pointon member 6 oppositepointez' 34 (attached to plate 2) when the end ofv the vsheet attainsany given distance from the printing point, by making said member anindex-carrier and supplying it with suitable indices, the distance 4tromthe printingpoint to the end of the sheet, or' to a point 'alknowndistance therefrom, can be indicated from thetime the paper-feeler is'released until 'the sheet leaves the machine. As the carrier il beginsits sheetsynchronized movement at a point. intermediate in the printingof the sheet and at a point moreover the distance oit which trom the endof the sheet is not obvious nor readily calculablqythe'- numeralbeginning such/a series will be conveniently esta lished in the firstinstance by experiment. lt is to .oe noted th t the indicating surfaceupon carrier is divided into two segments, onlT one or which, that shownin the drawings as dart; colorechis risible to the operasr eheedditional indicating means whereby ..i n* hell after the completion ot apredetermined amount of matter on the page,

Figs. and 11 represent a modification in the arrangement and form of thepaper cont-rolled parts of my device.V In this arrangement frameextension l5 attached to the framed? bears inwardly projecting pin e. Asleeve 211 isjournalcd upon this pin, mounted upon which are the weight663 tixedly. paper-feeler 281`tixedly, and collar 105 xedly, and thesuper-sleeve 104 loosely, the said super-sleeve hearing in its turn thexcdly attached cam-stop 1f supplied with a cam surface 301. Cam-stop1.ra is also supplied with a lug to cooperatel with a projection (32Minweight 663, so that when pressed in one direct-ion it will actrotatively upon sleeve 211, but not when pressed in the other.

past stop 15a. Vveight 66 serves the purpose of restoring` the stop 15aand paper feeler 281 into initial position. Paper-feeler 281 consists ofan upper part bearing-pin 23 and a lower part mortised therein andjour-A naled upon said pin, lug 65 and mortise-y lo'evel 24 cooperatingto limit the movement of said parts on one direction. to facilitatehacking-irpef the sheet.l Finger-stop k4t2 (Figi: 11) attached against ashoulder. .of pin 2()a hy the retaining nut 20,on said pin is providedto engage uponsaid paper-tecleal to prevent displacement thereof. Bymeans of the holt 19 an auxiliary paper-support 82 is clamped uponbrace-rod 18, said support vcooperatingr with the edge otpaper-tahle 8to form a slot 4e, into which the paper-feeler has its path.yShield-pointer 34e is attached directly to frame 47. In other respectsthe structure of this embodiment is' like that alrc'aly described, andits operation is essen'- tially the saine. i

Figs. 12 'and 13 represent another moditication in which cam-stop 15 andarm 32 ot Fig. 3 are combined in thecam-arm 15", hearing' paper-feelin'2S. Projection 14 aotinfn' upon this cani-arm alonel cam surface 3Uactuatcs paper-teder 2H into slot l in paper-support 8, attached hyholt- 19 upon rod 18. Instead of using spring 66 of Fig. 1 to return thepaper-freeler into initial posit-ion use a tailcam 29, which when en1gaged by projection 1a lifts cam-arm 15b out ot slot il toward theplaten until the parts atlectcd are well past the center ot gravity,after which they will tall by their own weight into initial position. inother respects the structure and operation of this torni or the deviceis essentially like that of the first form described.

Figs. 14 and 15 represent still another modification in the form anddisposition of the paper controlled parts. Platen frame 4l Y. hears theinwardly projecting ears 49 supporting pin 201, which serves as an axlefor the vertical lever-stop 152 supplied with a cani surface 30C. Thatis to say, the axis ci. leiser-stop 152 vis perpendicular to a radialliuc drawn through axis ot the member 6. I prefer to .give it a verticalposition, or one substantially vertical. The said vertical lever-stop152 has attached to it a paper-eeler which has a path through slot 4 inpaper-table 8. A spring 661 (Fig. 15) is used to return the paper-feelerout vof the slot and into initial position. l prefer to slope thcpaper-teeler diagonally upward 'for the purpose of more smoothly guidingthe lmcking-up bottoni edge of the sheet out under the paper-contactingportion of the isoler. This, however, is not essential. It is to benoted that, while desirable, the cam contour on stop 152 is notessential to the operation ot this form ofthe device, nor to that of theforms shown in Figs. 1 and 10.

Fig. 16 represents stiil another modification, showing how the cam-stopand its co` operating rider may be interchanged, cam 30% here revolvingin unison with member 6 and acting upon an inwardly projecting pin 1d"onarni 153, journaled on pin 20c inwardly extending from platen-frame47, not shown in this ligure. Said. arm bears the inwardly projecting,`paper-feeler 28, having an action into slot 4C in paper-table 8. Aspring (36, h cld at one end by a pin 82,011

. platen frame 4T and at the other by pin 83 on arm 152. serves toreturn paper-feeler Q8 t n s n out of slot 4 and into first positionagainst the platen. A ley pin is used in this modification to insureunison movement of spring 7 with member 6. instead ot placing piu 68 inone of the seats 67 on disk 25 asin Figs. l and 9, I place it in one ofthe threaded seats 67 on cam 301. The construction in other respects isessentially as has been described-in connection with the early figures.The operation of this modification is as tollows: Cani 15:3 through projcction if@ actuatcs paper-tceler 2S against the sheet, and through thepaper-teeler is then stopped bythe Jet. the attached meniher 6 beingthus detained in initialJ-)osiv 'l tion. when the sheet passes on fromunder the paper-tpeler, member 6 is released as before, and through 'thesaid member the several indicating means are eventually called intooperation.

Figs. `1'?, 18 and 19 represent another modification in the form of mycam-actuator. In this modication arm 152 bearing 'papenfeeler 28 isjournaled as before on inwardly-projecting pin 20 on platen-frame 47(not shown in these figures). 'Paperfeeler 28 has an action into slot din paper table 8. Spring 662 bearing against pin-S2 on platen frame 4:7`and against pin 8 3 on lever 152 tends to actuate paper-eeler Z8against sheet 45, instead of away from it, the paper-eeler beingreturned to initial position against the pressure of spring 662 by theaction of cam 302 upon inwardly pro jecting pin 142. The said cam 302may be given unison movement with member 62 through Aspring 72, thespring and cam being connected conveniently hy means of rivets 61 and akeypin 60 insuring unison rotation of the spring with member 62. In oneof the threaded seats 672 on said C un is screwed the outwardlyprojecting pin 68. Lever 152 bears a stop 154, which at times has aposition in the path of projection 14 on member 62. Spring 7 a pressessaid inember into frictional connection with the platen by bearing uponan inner shoulder thereof under the pressure of thrust-collar 33. Inother respects the structure is as has been described in connection withthe early gures. 'lhe action of the modification is as follows:Frictionally connected member 62 moving with the platen brings the swellor bosom pf cam 302 under pin 142, thus raising paperfeeler 28 into theposition shown in Fig. 17. The sheet is then inserted. As the platen isrotated, the slope of the cam is brought under pin 142, and paper-feeler2 8, under the actuation of4 spring 662 upon arm 153, `is loweredagainst the sheet and detained by it. In this position of partsstop'ltfxon said arm lies in the path of projection 14. Further rotationof the platen brings projection 14 against stop 154, and member 62, no

longer able to rotate with the. platen, is held detained until the endof the sheet passes from over slot 4.7 and releases paper-eeler 2S.It'willbe'seenthat when the end of the sheet clears the said slot,paper-feeler 28v stop 154. The action of spring 662 is iniso,

tended to he very light, in order that cam 3tlg may perform its workwith little res1stance.

The devices shown in the drawings and described herein are part ot aseries of closet;Y related inventions or improvements which arepresented in a number of cti-pending applications for Letters Patenttiled by me. The said devices have a number ot' genral objects in commonwith those forming `the subject matter ot dilierent applications 1n thesaid series, and to a certain extent embody and utilize variousprinciples and features which are common to devices shown and describedin one or another of the said applications.
